RETAINER FOR RIBBON-ROLLS.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed July 30, 1904. Renewed June 28, 1905. Serial No. 267,450.

of retainers or holders for use upon ribbonrolls adapted to prevent the unwinding of the ribbon. Its object has been to improve upon previous constructions of such devices and also to simplify their construction and lessen the cost of manufacture.

The nature of the invention is fully disclosed in the description given below and also inthe accompanying. drawings, in which Figure 1 is an elevation of a roll of ribbon to which my improved retainer has been applied. Fig. 2 is a partial section of the roll on the line 2 2 of Fig. 1. Fig. 3 is an edge view of the retainer detached, and Fig. Iis a perspective of the clip.

Referring to said drawings, it will be seen that my holder is formed from spring-wire, and it is made in one piece and is preferably bent into the shape shown in the drawings.

The portion marked 5 and 6 forms the main body of the device and sets down and presses on the outside of the ribbon. One end of the wire is bent over to form a lateral wing, as shown at 7 This wing is adapted to be inserted behind one or more of the folds of the ribbon, as particularly shown at Fig. 2, and serves as a means of attaching the device to the roll. In order that this wing may present no points or projections calculated to catch into or roughen the ribbon in any way, the metal used informing the wing is doubled upon itself, as shown at 8, so that its extreme point 9 may lie under the top bend 10. The wing is thus made in the form of a loop, which gives it the lateral Width necessary to prevent any turning or rocking by the main body upon the outside of the ribbon. This feature is desirable because at the bottom of the main stem or body a nub or enlargement 11 is formed, which should always stand out radially from the surface of the roll, as it is intended to aflord a means of detaching the retainer so as to carry the wing between the folds of the ribbon. The nub is formed by turning the point of the wire over upon itself, as plainly shown, the bending being in a plane at right angles to the plane of the retainingloop. By this construction the nub is always positioned so that it stands outward from the roll and is conveniently caught by the thumb when the retainer is to be removed, and it cannot depart from this position, because the wing or loop 7 necessarily assumes a position parallel to the folds of the ribbon and holds the body against any rocking, which would carry the nub down from its proper outstanding position.

In order that the lower end of the body may be made to press upon the ribbon firmly, I impart a bend to the body, which is illustrated at Figs. 3 and 4:, the bend being such as to raise the central portion slightly from the surface of the ribbon. This bend, which occurs at 12, imparts a spring action to the lower end of the body, and when the retainer is in use the body straightens out,as seen at Fig. 2.

It will be noted that my device is extremely simple and requires but little metal and that it is easily inserted and as easily removed; also, that when in the roll it aifords no practical obstruction to the piling or packing of the rolls, as the part which projects to the greatest extent from the surface of the roll is the nub 11; also, that no part of the device is adapted to scratch or injure the ribbon in any way. The ribbon is shown at Figs. 1 and 2 at 13, and the paper usually wound with it is shown at 14. Y

The body of the device is formed, it will be noticed, from a substantially straight piece of wire, and consequently unless controlled by the wing would be free to turn on its axis, and if it were permitted to thus turn sufficient pressure could not be brought to bear upon the surface of the ribbon to hold it in place and the nub would be frequently brought into a position parallel with the surface of the roll, in which case the user would have only the thickness of the wire to push against when removing the retainer. The importance, therefore, of keeping the nub, with its enlargement,'standing radially on the roll will be apparent. It will further be noticed that the lateral wing by which the body is prevented from turning consists of two substantially parallel portions of wire separated from each other a suflicient distance to give them the width necessary not only to prevent the body of the retainer from turning, but also outside of the roll, and a lateral Wing or loop adapted to enter between the folds of the ribbon and serve to hold the retainer in position.
